The Umami-kofun Tumuli Cluster (Tumuli Cluster around Umami-kyuryo Hill) (馬見古墳群)
The Umami-kofun Tumuli Cluster was constructed around the Umami-kyuryo Hill which was stretched from Kawai Town, Koryo Town of Kitakatsuragi County to Yamato Takada City, Nara Prefecture, in the southwest area of the Nara Basin. It was one of the most famous tumuli clusters in Nara Prefecture, consisting of three groups: North group, Middle group and South group.
It was constructed between the end of fourth century and sixth century. There is a view that it is the cemetery area of the Katsuragi clan, which was an ancient local ruling family. In the Katsuragi region, construction of famous tumulus started from the middle of the early Kofun period (Tumulus period). In the mid-early period to the middle period, tumuli of more than 200 meters long were constructed.
